Mental health and socio-cognitive predictors of adherence to COVID-19 social distancing rules in adolescents in England.

The COVID-19 pandemic prompted governments worldwide to introduce social distancing measures, including school closures and restrictions on in-person socialising. However, adherence to social distancing was challenging for many - particularly adolescents, for whom social interaction is crucial for development. The current study aimed to identify individual-level influences on adherence to social distancing in a longitudinal sample of adolescents aged 11-20 years in England, who took part in a randomised controlled trial.

DNA-elucidated life cycle of a highly pathogenic avian nematode: (Spirurida: Acuariidae) and its morphological development from infective third-stage larva to adult.

Gibson, 1968 is an acuariid nematode associated with lethal cases of streptocarosis of diverse aquatic birds in North America and Europe. This study reports as an agent causing severe and fatal necrosis of the oesophagus and proventriculus of anatids, i.e.

Hidden Causes of Variation in Offspring Reproductive Value: Negative Effects of Maternal Breeding Age on Offspring Telomere Length Persist Undiminished Across Multiple Generations.

Offspring of older breeders frequently show reduced longevity, which has been linked to shorter offspring telomere length. It is currently unknown whether such telomere reduction persists beyond a single generation, as would be the case if germline transmission is involved. In a within-grandmother, multi-generational study using zebra finches, we show that the shorter telomeres observed in F1 offspring of older mothers are still present in the F2 generation even when the breeding age of their F1 mothers is young.

Guanine nucleotide exchange factors and colon neoplasia.

Despite many diagnostic and therapeutic advances, colorectal cancer (CRC) remains the second leading cause of cancer death for men and women in the United States. Alarmingly, for reasons currently unknown, the demographics of this disease have shifted towards a younger population. Hence, understanding the molecular mechanisms underlying CRC initiation and progression and leveraging these findings for therapeutic purposes remains a priority.
